CALKING RING Filed Dec 17. 1 928 INVENTOR #67797 Bart Patented June 17, 1930 away 0,; Bum, on LAiNGSBURGr, 'izrronrenn, essrenoaor ONE-HALF. To oz-marina W. LEE, OF'IDETROIT MICHIGAN 4 v GALKING nine Application filed December 17, was serial n seaen. M a v lar-bodies and refers part'icularlyto devices for-Lise in the sealing of joints.

'An object of the invention. is to provide a device} adapted to greatly facilitate the sealingoperation. This device maybroadly be considered aclosure formold cavit es and 111 .thespecific form shown a'nd described herein consists of a ring-shaped member which may be termed. a calking ring and which is adapted to be sprung over one ofthe parts to be joined andto be moved into engagement with the other part and toform therewith a mold for receiving the sealing material such as molten metal, this calking ring being adapted to be removed as soon as the metal has hardened and subsequently applied to otherjoints.

lVith these and other objects in view the invention consists in certain novel features of construction, combinations and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the drawings: 7 Figure 1 1s a top plan View of a pair of V pipe sections ready to be joined together and my calking ring applied thereto in operative position; 7 i

Figure 2 is a perspective View of the spring metal core. I I

Referrlng now to the drawings and particularly to Figure 1, the numerals l and 2 designate pipe sections which are to be joined togetheig'the section 2 being provided atone end with the usual enlarged hub portion 3 within whichis received the end portion of l the section 1. This is the' usual construction of such sections and the arrangement issuch that an'annular space or mold cavity is provided between the outer face ofthe section 1 and the inner face of the hub to permit a sealing material such as moltenleacl to be poured in the opening and hardened. The

. usual procedure is to clamp an asbestos or oakum rope around the annular opening to complete the mold for the molten metal or to close the annular opening with putty :orclay, which also completes the mold. Botlrof these annular'space between the sections.

methods are slow and ineihcient, however, and

ing 6 of non-combustiblematerial such as as bestos {within which the-wire is 'imbeddeoh T his construction gives to the calking' ring a suificient springiness s so that it may be easily attached toand removed from a pipe section by springingthe ends of the ringapart. In the present instance the asbestos cover-ing is shown as beingsquare-in cross section so that when the ring is slipped upon the sec-- tion 1 and moved into engagement with the flat end of the hubQit will form a seal therewith. The ring, when applied to the pipe sections, closes the annular opening or space and forms with the hub, a mold for receiving themoltenmetal.

In order to provideia pour-mg spout or opening; the ring is providedwitha lateral- 1y ofiset portion Tadjacent one end, a-portion l 8 projecting] fromfthe portion-7 and lying parallel to-the main body of the ring, and

an extreme end portion 9 directed inwardly;

and adapted to slidably engage the other end 10 0f the ring,- It will beapparent that dif ferent sized rings; will be'made for different sizes of pipes, and for' a particular size of pipe the ring-adapted therefor is so designed that the, end portions will. li e substantially in the positionshown in Figure 1 so that the ring will form with-the hub an opening l'l through which the molten metal may be easi 1y and quickly poured and directed to the ItfWillbe apparentthat any slight curacies'i'nthe-size of a pipe section is com-- pensated-for by the arrangement of the end portionsqofthe ring, Therefore if a pipe sectionis sligl'itlylarger or smaller, the overlapping portion 9 may slide relative tothe end portion1O to compensate forsuch inacg curacies. Inorder that'a tight fit or joint be forme i e weej j l h e dp t ons f T the: ring, it is" formed so that these; portions are 'urg'ed together so that" while the portion 9 may be moved relative to the end 10 there i V will always be a tight joint between these parts which will prevent any of the molten metal "from escaping.

After the sealing material has been poured through the opening 11, it is permitted to harden suiiiciently and the end portions of the ring are sprung apart to permit the removal of the ring from the section 1, whereupon it may be subsequently utilized in the sealing of additional joints. r

While I have specifically shown and described mycalking ring as being applied topipe sections, it will be apparent that this is not the only use to which it may be subjected and that the same is equally eflicient in babbitting bearings on shafting.

In fact the use of my ring is a decided improvement onthe usual method of sealing the joint with putty or clay and pouring the metal through the oilholeon top of the boxing. VVhen a calking ring is used, the metal will be poured at the endror" the boxing, permitting the air to escape through the oil hole 7 and thus provide a smoother bearing in which air pits are eliminated. V

I wish it. tobe understood that I do not limit my sallring ringto the uses mentioned 7 above and thatit may be utilized wherever it is desired to provide a closure for mold cavities surrounding annular bodies.

1 What I claim as my invention is: 1. A closure for mold cavities surrounding annular bodies comprising a split ringshaped member adapted to be sprung over the body and to close the cavity, said vmember being provided at one of its ends with a laterally offset portion that forms with the other end an opening. through which the material to be molded, may be poured.

2. A caliring ring-comprising a split ring of yieldable material having a laterally offset substantially U-shape portion, and a covering for said ring and ofiset portion, the covering for a portion of the ring and for said offset portion forming a pouring spout.

. 3. A calking ring comprising a split metal ring having a laterally ofiset substantially U-shape portion at one end, and acovering of asbestos 'forsaid split ring and offset ,portion, the covering-for a portion-of the ring overlapping and cooperating with the ofiset portion aforesaid to form a pouring spout.

i at one side otthe'split, and the other side of 4. device of the classdescribed comprise ing a transversely split ring-shaped member of yieldable material having a'laterally offset substantially U-shaped portion opening site ends thereof spaced apart, and having a substantially U-shaped portion bridging the gap between the spaced ends aforesaid, said U-shaped portion opening toward and cooperating with the space or gap between said ends to form a pouring spout.

6. A callring ring comprising a transverse- 1y split metal ring, and a cover of non-combustible material for said split ring having a substantially U-shaped laterally projecting 'oiiset portion opening toward and forming with spaced portions of the covering on said ring a pouring spout.

7. A callring ring comprising a transverselysplit metal ring having a laterally projecting substantially U-shaped offset portion, and a covering for said ring and offset portion formed of non-combustible material, said covering throughout its'length being substantially square-shape in cross section, and the covering for the offset portion cooperating with the covering for the ring to term a pouring spout.

lntestimony whereof I afiix my signature.
